STOCK -TRUCK.

SPECIFICATION forming part of Letters Patent 1\l'o. 603,676, dated May 10, 1898. Application filed July 20,1897. Serial No. 645,280. on made.)

To all whom it may concern:

Be it known that I, GEORGE P. CLARK, a citizen of the United States, residing in Windsor Looks, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Stock-Trucks, of

which the following is a specification.

This invention relates to stock trucks adapted for use in paper-mills and similar places for conveying stock or paper-pulp from one place to another in the mill; and it comprehends, essentially, a transportable truck consisting of a tilting body having reticulated or perforated sides, thereby topermit any liquid, such as water, in the mass within said body to percolate or trickle through the openings or holes in the sides, manually-operated means being preferably furnished to effect the discharge of the contents of the body by tilting the same when desired, the frame of the truck being preferably mounted on wheels or rollers, so that the device can be readily transported from place to place.

' In the drawings accompanying and forming part of this specification, Figure l is a per spective view of my stock-truck, showing the body in its normal position; and Fig. 2 is a similar view illustrating the body tilted.

Similar characters designate like'parts in both figures of the drawings.

My stock-truck comprehends as a part thereof a tilting body, such as B, hereinafter more particularly described, supported for oscillation by a suitable frame, as F. The frame F in the form represented consists of a base portion 2 of rectangular shape, composed of a series of beams 3, 4, 5, and 6, the opposite edges of the transverse beams 5 and 6 being squared OE and fitted against the longitudinal beams 3 and 4, and a series of vertical posts 7, 8, 9, and 10, whose butts fit against the other frame members, i

The posts 8 and 10 are somewhat higher than the companion posts 7 and 9 fora reason that will hereinafter appear.

The posts or uprights 7 and 8 are connected by the bar 12, attached at its opposite ends in some suitable manner to these parts, the posts 9 and 10 being joined by a similar bar 13 in a like manner.

The several members of the base part 2 of the frame F and the vertical posts or uprights 7, 8, 9, and 10 are secured together by a series of angular brackets or braces 14, 15, 16, and 17 The brackets being the same in construction and the one denoted by 16 showing the construction clearly, it will be specifically described.

The bracket 16 embodies a substantially L-shaped body portion 17, having a longitu- 6o dinal flange 18, said flange in turn being provided with a short transverse flange 19. The main or body portion 17' of the bracket is secured by screws or equivalent devices to two members of-the frame F, as the parts 6 and 10, the flanges 18 and 19 being likewise secured to another member of said frame, as

the beam 4. By reason of the construction specified the several parts of the frame may be joined together with proniptness and exactness, thereby obviating the necessity of dovetailing or mortising and tenoning the several frame members to each other, as is customary in this class of structures.

The frame members 3 and 4 have secured thereto at a point intermediate their ends the hangers or bearings 20 and 21, in whichthe opposite ends of the shaft or axle 22 is journaled, said shaft being provided with the wheels 23 and 24, by which the truck can be rolled from place to place, the transverse members 5 and 6 of the frame being provided with the caster or guide wheels 25 and 26, whose frames 27 and 28, respectively, are attached to the said transverse frame members by screws or similar fastening devices.

The body B of the truck is composed of'the front and back portions 30 and 31, said front portion 30 fitting against and being secured to the lower edge of the back portion 31, the latter being curved, and the reticulated or perforated sides 32 and 33, secured between the front and back portions 30 and 31, respectively, of the body, so as to form substantially a tank to receive a large quantity 5 of paper-pulp or analogous substance, the liquid or water from which can trickle or flow through the series of openings 34in the sides 32 and 33 of the body. r

The reticulated sides 32 and 33 of the body B are furnished, near one corner thereof, with the laterally-extending journals or trunnions 35, having wing-pieces 37, secured to said reticulated sides and working in the pockets or bearings 38 at the lower ends of the tie- I05 bars 12 and 13.

In Fig. 1 the body B of the truck is shown occupying its normal position, so that it can be filled with a mass of pulp or other substance, this operation being more easily effected by dropping the flap 40, forming a part of the front wall of the body and hinged to the main section 41 of said wall, as at 42 and 43, respectively. The flap abuts against the flanges 44 and 45 on the reticulated sections 32 and 33, respectively, and is held in its normal position in line with the wall-section 41 by a nut 46 in engagement with the threaded stud 47 on the flange 45. By removing the nut the flap 40 may be tilted down, as will be apparent.

Manually-operated means will be provided for eifecting the discharge of the contents of the body Bby tilting the same, and the means shown for this purpose will now be described. A longitudinal shaft is shown at 50, its opposite ends being journaled in bearings at the upper extremities of the tie-bars 12 and 13, respectively, said shaft being provided near its opposite ends with the sprocket-wheels 51 and 52, around which the sprocket-chains 53 and 54 are passed, said chains being connected at their lower ends with the projections 55 and 56, secured to the opposite lower ends of the body B, the two chains shown being in contact with the curved back piece or wall 31 of the body in Fig. 1, so that when the shaft 50 is rotated or turned the body, by reason of its connections with said shaft, will be tilted, as represented in Fig. 2, to permit the contents or material in said body to gravitate therefrom, as is apparent.

The free ends of the two chains 53 and 54 have secured to them the balance-weights 57,

adapted to maintain said chains taut. The shaft 50 is rotated through the intervention of worm-gearing, the worm-gear of which is secured to one end of said shaft.

The spiral screw 61 is on the shaft 62, carried by the bracket 62, near the upper end of the upright or post 8, said shaft being provided with a crank-arm 64, the handle of which is denoted by 65. By manipulating the crank-arm 64 the body B can be readily tilted or shifted.

It will be obvious that my improved device can be used not only for transporting stock or pulp in paper-mills, but it can be employed equally as well for carrying Wool, cotton, and other material in dye-houses or textile-factories, or it can be utilized as an effective substitute for the hand-baskets now generally used for various kinds of millwork.
